Please post pics of your set up. This thread will show you how: https://ball-pythons.net/forums/show...-Post-Pictures. In addition, what are the warm and cool side temperatures? Aside from the spikes, what's the level of her humidity? The more info we have the better the advice we'll give.
I suggest holding off on feeding at least until Sunday. Repeated attempts to feed a snake that doesn't want to eat will stress your snake and make her less likely to feed. Between now and then, you'll want to get the temps and humidity dialed in. She'll feel much better eating if her temps and humidity are correct.
I understand your anxiety. Been there. This is the worst part. I assure you, once you've got everything in the enclosure properly set up, it's pretty much easy sailing.
